Common Use

Brand Viagra was developed by the pharmaceutical company Pfizer. The main component of Brand Viagra is Sildenafil Citrate.

Sildenafil Citrate affects the response to sexual stimulation. It works by enhancing smooth muscle relaxation using nitric oxide, a chemical normally released during sexual stimulation. This relaxation increases blood flow to the penis, facilitating an erection.

Sildenafil Citrate is used to treat erectile dysfunction (impotence) in men and pulmonary arterial hypertension.

Sildenafil Citrate may also be used for other purposes not listed here.

Dosage and Direction

The recommended dose is typically 50 mg, taken approximately 30 minutes to 1 hour before sexual activity. Do not take Viagra more than once a day.

A high-fat meal may delay the drug's effect. Avoid consuming grapefruit or grapefruit juice while using Sildenafil Citrate.
